ipv6: Refactor exception functions Before moving exception bucket from fib6_info to fib6_nh, refactor rt6_flush_exceptions, rt6_remove_exception_rt, rt6_mtu_change_route, and rt6_update_exception_stamp_rt. In all 3 cases, move the primary logic into a new helper that starts with fib6_nh_. The latter 3 functions still take a fib6_info; this will be changed to fib6_nh in the next patch. In the case of rt6_mtu_change_route, move the fib6_metric_locked out as a standalone check - no need to call the new function if the fib entry has the mtu locked. Also, add fib6_info to rt6_mtu_change_arg as a way of passing the fib entry to the new helper. No functional change intended. The goal here is to make the next patch easier to review by moving existing lookup logic for each to new helpers. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.
